Why Your Form Auto-Reply Email Did Not Arrive
Short summary
Form auto-reply failures typically result from configuration, delivery, or inbox-placement issues rather than simple on/off switches. Systematically debug across eight states: configuration, recipient field mapping, send-rule matching, job creation, provider acceptance, delivery status, mailbox placement, and respondent action. Use email authentication (SPF/DKIM/DMARC), trace provider logs, guide recipients to check spam folders, and set Reply-To headers correctly.
